A
Thinking of ways to reduce the impact of pollution is on everyone's minds. This is how 14-year-old Vinisha Umashankar, a student of SKP Vanitha International School in Tamil Nadu, is doing her part to save the planet.
In October 2018, Vinisha saw an ironing worker throw a few pieces of hot charcoal on the pathway and then pour water on it. When asked why he was doing that, he explained that he was cooling the hot charcoal before he could throw it into the dustbin.
On reaching home, she did a little quick research on the Internet and learnt that to make 1kg of charcoal, 12 fully-grown trees need to be cut down. Apart from that, burning of coal emits harmful gases like carbon monoxide. That is when she started to think of alternative sources of heat to iron clothes, and the first idea that popped into her mind was solar energy. While Vinisha knew that solar energy can be harnessed (利用)to generate power, she did not know how. So she referred to college-level Physics books.
By September 2019, Vinisha had finished working on the technical paper. Impressed with her work, her father submitted her paper to different competitions and soon it was picked up by a group of engineers at the National Innovation Foundation, Ahmedabad, who helped make the prototype (雏形).The ironing cart has solar panels as the roof, which is connected to 100ah battery. Once the battery is fully charged it will power the steam iron box for six hours. Apart from that, the cart has USB ports which can be used to charge mobile phones, too.
The approximate cost of this ironing cart is yet to be determined, and for the future, Vinisha hopes to use her prize money to deploy (配置)a few ironing carts in her hometown and get feedback from the ironing workers.
21. Which of the following best describes Vinisha?
A. Creative. B. Intelligent. C. Determined. D. Energetic.
22. What did Vinisha's father do to help her?
A. He made the prototype of the solar ironing cart.
B. He wrote the technical paper of the solar ironing cart.
C. He handed in her technical paper to various contests.
D. He looked for renewable energy to iron clothes.

推理判断题。根据第三段“That is when she started to think of alternative sources of heat to iron clothes, and the first idea that popped into her mind was solar energy. While Vinisha knew that solar energy can be harnessed (利用)to generate power, she did not know how. So she referred to college-level Physics books. （就在那时，她开始考虑熨烫衣服的替代热源，第一个闪现在她脑海的想法是太阳能。虽然Vinisha知道太阳能可以用来发电，但她不知道如何利用。所以她参考了大学水平的物理书籍。）”可知， Vinisha想要找熨烫衣服的替代热源，然后考虑到太阳能可以替代，并且能够减少污染，由此推断，她是一个很有想法的人，即创造力，故选A。

推理判断题。根据第三段“On reaching home, she did a little quick research on the Internet and learnt that to make 1kg of charcoal, 12 fully-grown trees need to be cut down. Apart from that, burning of coal emits harmful gases like carbon monoxide. That is when she started to think of alternative sources of heat to iron clothes, and the first idea that popped into her mind was solar energy.（回到家后，她在网上做了一些快速的调查，了解到要制作1公斤的木炭，需要砍掉12棵成年的树。除此之外，燃烧煤炭会排放一氧化碳等有害气体。就在那时，她开始考虑熨烫衣服的替代热源，第一个闪现在她脑海的想法是太阳能。）” 以及第四段“The ironing cart has solar panels as the roof, which is connected to 100ah battery. Once the battery is fully charged it will power the steam iron box for six hours. （熨衣车有太阳能电池板作为棚顶，它连接到100ah的电池。一旦电池充满电，它将为蒸汽熨斗箱供电6个小时。）”可知， Vinisha的太阳能熨衣车是为了代替木炭而研制的，所以它能够帮助减少木炭的使用，故选D。
